First off I'm not trying to stir up old dung.........I didn't title this one lean cruse
as per not upset anybody. But here goes
GM went through the trouble of checking the platform because of the EPA (bastard EPA)

The ONLY way around this is to modify that platform check routine, or change the platofrm type to Holden in the calibrations (we don't allow you to do that)

so why do we have G1206 ??

Just wondering
